具有Robin条件的磁Schrodinger算子的半经典迹渐近性

Semi-classical trace asymptotics for magnetic Schrodinger operators with Robin condition

Ayman Kachmar, Marwa Nasrallah

摘要:

本文计算了一类磁薛定谔算子在有边界区域上的本征值和及本征值的个数。在算子的定义域中的函数满足(磁)罗宾条件。计算在半经典渐近极限下是有效的,有关的本征值对应于局域在区域边界附近的本征态。我们推导的公式显示了边界和边界条件的影响,并且在边界函数弱正则性假设下是有效的。我们的方法依赖于三个要点:减少到边界;边界相干态的建设;处理的边界项作为一个表面电势和控制的各种Lieb-Thirring不等式的错误。

英文摘要:

We compute the sum and number of eigenvalues for a certain class of magnetic Schrodinger operators in a domain with boundary. Functions in the domain of the operator satisfy a (magnetic) Robin condition. The calculations are valid in the semi-classical asymptotic limit and the eigenvalues concerned correspond to eigenstates localized near the boundary of the domain. The formulas we derive display the influence of the boundary and the boundary condition and are valid under a weak regularity assumption of the boundary function. Our approach relies on three main points: reduction to the boundary; construction of boundary coherent states; handling the boundary term as a surface electric potential and controlling the errors by various Lieb-Thirring inequalities.
